A pilot television series reached some 100,000 Ontario elementary school students with a series on meteorology and ecology. Flexible interactive opportunities (via broadcast, newsletter, phone, mail, personal contact) were utilized; resources not available were provided, while at the same time local options were preserved and encouraged. Use of the phone was limited during the pilot to protect against jamming the system and against incurring project costs beyond means. A questionnaire surveyed student and faculty opinion on the subject of involvement and interaction. The student TV module was found to be the most important interactive component. Ninety-four percent of the teachers responding to a followup questionnaire said the series was more useful than an ordinary educational television series. (WCM)
